Definitions

  • the present invention relates generally to the field of children's pla ⁇ structures and, in particular, to interactive play structures for safely entertaining and educating young and intermediate age children and adults.
  • Participatory or interactive play structures that is, play structures that allow play participants to actively participate in creating desired effects, are particularly desirable because of their widely recognized entertainment and educational benefits. See, for example, my U.S. Patent No. 5,194,048 and related design patent 0330,579. These patents first disclosed the concept of interactive or participatory play in the context of a water park attraction. Many large-scale successful commercial water parks now incorporate interactive play structures of the type disclosed in my U.S. Patent No. 5,194,048. Families that have patronized these commercial water parks have discovered for themselves the valuable entertainment and educational benefits that interactive play provides.
  • a typical dry play structure may include a padded framework and cushioned floors defining a variety of play elements or areas. Slides, tunnels, net bridges, and ladders may be used to interconnect the various play elements and play areas together so that play participants can traverse from one play element or area to the next.
  • an especially exciting and entertaining play activity supported by a wet play structure involves shooting a stream of water at selected targets and/or other play participants. This usually entails some form of a water cannon, water gun, squirt gun, spray hose or the like, which pla ⁇ participants can operate to surprise other play participants or to achieve desired effects.
  • Such participatory play activities provide particular benefits in developing children's motor skills and hand-eye coordination. It also provides endless fun for play participants, who enjoy the challenge of trying to hit various targets and/or one another.
  • Water as a primary pla ⁇ media lends itself readily to facilitating such pla ⁇ activities because it is easil ⁇ extruded through a nozzle or otherwise formed into various projecting streams or other entertaining shapes and/or patterns. Also, water can be collected and recirculated to the various pla ⁇ elements using pumps or other efficient and commercially available recirculating and transporting means.
  • dr ⁇ pla ⁇ media typically involves the use of discrete articles having a defined size, shape and mass which remain constant during flight and upon impact.
  • water is easil ⁇ regulated at the source to ensure that the pressure and impact velocit ⁇ of the resulting stream remains within predetermined safe parameters, the impact velocit ⁇ of discrete projectiles is not so easil ⁇ regulated.
  • the prior art does not satisfactoril ⁇ address the problem of how to collect and recirculate a non-fluid pla ⁇ media so as to support such pla ⁇ activities in a dr ⁇ pla ⁇ structure.
  • An object of the present invention therefore, is to provide a dr ⁇ interactive play structure to provide shooting and targeting play dynamics and interactive play capabilities using impact-safe dry foam projectiles (or other impact- safe projectiles). Another object of the present invention is to provide various safe and durable devices for launching or propelling dry play media at various targets and/or other pla ⁇ participants. Another object of the present invention is to provide an impact-safe pla ⁇ media particularly adapted for use in a dry play structure for shooting and targeting play dynamics and interactive pla ⁇ capabilities. Another object of the present invention is to provide various automated and/or pla ⁇ participant operated conve ⁇ ers for collecting, recirculating and/or transporting dr ⁇ play media to various play areas or interactive play elements disposed throughout a pla ⁇ structure.
  • Another object of the present invention is to facilitate various interactive play activities which incorporate a wide range of fun and exciting mechanisms, such as springs, cams, pulleys, gears, and the like, all of which can be employed to provide an interactive play experience which is both fun and, at the same time, educational.

Certain pla ⁇ elements ma ⁇ use onl ⁇ certain sized balls, with filtering rela ⁇ s (not shown) in the conduits 124 permitting onl ⁇ certain sized balls to roll to certain pla ⁇ areas. A range of colors for the balls may also be used for visual appeal.
  • ball sizes and/or types ma ⁇ be color-coded as desired to indicate their use with particular pla ⁇ elements or in certain pla ⁇ zones and/or for facilitating their return to the proper areas when the ⁇ are removed.

  • spherical, bullet or dart shaped projectiles may be used to enhance the accuracy and/or distance of the play media when thrown or launched using a projectile launching apparatus.
  • Spherical balls may be dimpled, if desired, to improve their aerodynamic properties.

  • ball projectiles are preferabl ⁇ impact-safe -- that is, the size and mass of the ball projectile is preferabl ⁇ not so great as to produce a risk of injury to play participants upon impact, taking into account the impact velocit ⁇ and the material composition of the ball projectile. It has been found that a ball diameter of about 2 1 /. inches (6.3 cm) and a weight of about .15 oz. (4.25 grams) provides a particularly suitable compromise between these competing objectives. This correlates to a preferred EVA density of about 2 lbs/ft 3 (32 kg/m 3 ).
  • suitable pla ⁇ media 104 may include, without limitation, foam, plastic or rubber balls and similarly formed articles such as cubes, plates, discs, tubes, cones, rubber or foam bullets/arrows, the present invention not being limited to any particular preferred pla ⁇ media. These ma ⁇ be used alone or in combination with one another.
  • fl ⁇ ing discs such as FrisbeesTM
  • FrisbeesTM ma ⁇ be flung from one location on the pla ⁇ structure 100 while other pla ⁇ participants shoot at the discs using foam balls or suction-cup arrows.
  • Durable plastic or rubber pla ⁇ media are most preferable in an outdoor pia ⁇ structure where environmental exposure ma ⁇ prematurel ⁇ destro ⁇ or degrade the qualit ⁇ of certain pla ⁇ mediums such as foam balls.
  • Various interactive pla ⁇ elements are disposed in, on and/or around the pla ⁇ structure 100 to allow pla ⁇ participants 105 to create desired effects, as illustrated in FIGURES 1 -4.

Abstract

L'invention concerne un système (100) et une structure de jeu interactif, dans lesquels plusieurs éléments (200, 203, 220, 230, 240, 250, 270, 280, 290, 300, 310, 320) de jeu interactif sont prévus afin de produire divers effets voulus au moyen de balles (104) en mousse molle ou d'autres supports de jeu 'secs' appropriés. Dans un mode de réalisation, le système (100) de jeu interactif comporte une structure support (102) à plusieurs niveaux sur laquelle les éléments de jeu interactif sont placés. Ceux-ci permettent aux participants de produire des effets de jeu voulus à l'aide d'un support de jeu sec familier et amusant. Certains éléments (240) du jeu peuvent être des éléments de jeu polyvalents, en ce qu'ils reçoivent des supports de jeu provenant d'un premier effet (246) afin de créer un autre effet. Diverses installations de transport, divers dispositifs de recueil de supports de jeu, et divers mécanismes de retour (330, 332, 350, 360, 370, 380, 400, 420, 600, 630, 670, 720, 749, 799, 800) automatisés et/ou actionnés par les participants sont prévus dans toute la structure (100) pour recueillir et transporter les supports de jeu (104) d'une source, tel un bassin collecteur (750), vers les divers éléments de jeu interactif.
